Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shift device for a transmission for a vehicle of a type in which a select operation and a shift operation of a shift lever are transmitted to a transmission side through individual operating systems.

[0002]

2. Description of the Related Art Conventionally, this type of shift device is disclosed in, for example, Japanese Patent Laid-Open No. 63-8812. The shift lever of this publication is supported by a shaft for shifting operation with respect to the bracket. Further, this shift lever is configured to be selectable with a ball portion arranged below the shaft as a fulcrum.

[0003]

In the shift device of the above publication, since the shaft, which is the pivotal fulcrum of the shift lever during the shift operation and the select operation, and the ball portion are largely separated from each other, the shift lever is selected. The members of the shift operation system are also displaced by the operation. Therefore, the operation locus of the shift operation system member changes under the influence of the select operation, and when the detent mechanism for the shift operation is provided on the shift lever side, the friction that acts on the detent mechanism during the select operation is dealt with. There must be. Further, if the rotation fulcrums of the select operation and the shift operation are separated, a feeling of strangeness is caused in each operation, and the operation feeling is deteriorated.

A technical problem of the present invention is that the movement of the shift lever at the time of a select operation is not influenced on the shift operation system so that the operation loci of the members of the shift operation system are always kept constant and provided on the shift lever side. It is to simplify the structure of the detent mechanism and improve the feeling of each operation of select and shift.

[0005]

In order to solve the above-mentioned problems, a shift device for a vehicle transmission according to the present invention is constructed as follows. That is, in the shift device for a vehicle transmission, the shift force is transmitted to the transmission through the rotation of the selecting lever and the shifting lever that are individually interlocked with the shift lever's select operation and shift operation. The shifting lever is rotatably supported by the shift lever retainer by the shift shaft, and the axis of the select shaft formed integrally with the shifting lever is made orthogonal to the axis of the shift shaft in the same plane. The shift lever is supported on the select shaft so as to be rotatable in the select operation direction.

[0006]

According to this structure, when the shift lever is selected around the axis of the select shaft, the select force is transmitted to the transmission through the rotation of the selecting lever which is interlocked therewith. The movements of the shift lever and the selecting lever at this time do not have any influence on the shifting lever provided with the select shaft. That is, since the shifting lever does not move even by the selection operation, the operation locus of the shifting lever that rotates around the axis of the shift shaft by the shift operation of the shift lever is always constant. Even if the detent mechanism for shift operation is provided on the shift lever side, relative movement of the detent mechanism does not occur during the shift lever select operation, so there is no need to configure this detent mechanism to deal with slide friction or the like. , Its structure can be simplified. Since the axes of the select shaft and the shift shaft, which are pivotal fulcrums of the shift lever during the select operation and the shift operation, are orthogonal to each other in the same plane, the select operation and the shift operation are performed respectively. No sense of discomfort.

Is assembled. In other words, the retainer 20 is attached to the base plate 10 at the four corners thereof with the bolts 24 with the bush 22 and the collar 23 interposed therebetween, as is apparent from FIG.

FIG. 3 shows a sectional view as seen from the direction of arrow AA in FIG. As is apparent from this drawing, the shifting lever 30 has a sleeve portion 32 integrally formed at the upper end thereof, and the sleeve portion 32 is provided on both side frame portions of the shift lever retainer 20 with a bush 40 and a collar 41. Is rotatably supported by the shift shaft 38 with the interposition of. As shown in FIGS. 2 and 3, an end portion 73 of the inner cable 72 of the shifting cable 70 is coupled to the pin 34 formed at the lower end portion of the shifting lever 30. A cam plate 44 is fixed to the shifting lever 30 as shown in FIGS. 2 and 3, and the lower surface of the cam plate 44 has an uneven cam surface 4.
It is 5. A roller 48 is provided at the end of the plate spring 46 fixed to the base plate 10, and the roller 48 is pressed against the cam surface 45 of the cam plate 44 by the elastic force of the plate spring 46. Thereby, the detent mechanism 42 at the time of the shift operation, which will be described later, is performed.
Is configured.

FIG. 4 is a plan sectional view showing the supporting structure of the shifting lever 30. As is apparent from this drawing, the shifting lever 30 has a sleeve portion 32
The select shaft 36 extending from both sides to the front and rear sides of the vehicle is integrally formed, and the axis of the select shaft 36 and the axis of the shift shaft 38 are orthogonal to each other in the same plane. On the other hand, the shift lever 50 of the transmission is provided with a pair of supporting portions 53, which are separated from each other in the front-rear direction of the vehicle and a single arm 51 extending laterally, at a lower portion thereof. Then, the respective cylindrical portions 54 formed at the ends of the respective support portions 53
Are rotatably supported on the select shaft 36 via bushes 56 as shown in FIG. It should be noted that each tubular portion 54 is axially positioned by bolts 58 tightened at both ends of the select shaft 36 via a washer 59 and a collar portion of the bush 56.

FIG. 5 shows a sectional view as seen from the direction of arrow BB in FIG. As is clear from this drawing, the pair of brackets 12 provided integrally with the base plate 10 has a sleeve portion 61 formed at an intermediate portion of the selecting lever 60 with a bush 65 and a collar 66 interposed therebetween. Rotatably supported by a bolt 67. The selecting lever 60 is L-shaped as shown in FIG. 2, and the pin 64 formed at the end of the portion extending downward from the sleeve portion 61 has the shape shown in FIGS. 2 and 3. The end portion 83 of the inner cable 82 of the selecting cable 80 is coupled to the. An end portion of a portion extending laterally (toward the rear of the vehicle) from the sleeve portion 61 is an engaging portion 62 which is cut out in a U shape, and is provided at the tip of the arm 51 of the shift lever 50. The formed small ball portions 52 are connected via a bush 63. A select return spring 68 is provided on the outer periphery of the sleeve portion 61 of the selecting lever 60 so as to hold the selecting lever 60 at the position (select return position) shown in FIGS. 1 and 2, for example. It is provided.

In the shift device constructed as described above, when the shift lever 50 is selected in the direction of the arrow in FIG. 3, the shift lever 50 rotates about the axis of the select shaft 36. Therefore, the movement of the arm 51 at this time is transmitted from the small ball portion 52 to the selecting lever 60 via the bush 63, and the lever 60 resists the elasticity of the select return spring 68 and rotates around the axis of the bolt 67. Turn to. By the rotation of the selecting lever 60, the selecting operation is transmitted to the transmission side through the inner cable 82 of the selecting cable 80 which is pushed and pulled in conjunction with this.

On the other hand, when the shift lever 50 is shifted in the direction of the arrow in FIG. 2, this operating force is applied from the supporting portion 53 of the shift lever 50 via the bush 56 to the select shaft 36 of the shifting lever 30. Act on. As a result, the shifting lever 30 rotates together with the shift lever 50 about the axis of the shift shaft 38, and the shifting lever 30 shifts to the transmission side through the inner cable 72 of the shifting cable 70 that is pushed and pulled in conjunction with this. The operation is transmitted. At the time of this shift operation, the cam plate 44 of the detent mechanism 42 moves together with the rotation of the shifting lever 30, so that it is engaged with the central recess of the cam surface 45 as shown in FIG. The roller 48 of the leaf spring 46 selectively engages with either the left or right recess. This gives a feeling of moderation to the shift operation of the shift lever 50.

Select operation of the shift lever 50 is performed by
It has no effect on the shifting lever 30,
This shifting lever 30 does not move. Therefore, during the shift operation of the shift lever 50, the shifting lever 3 that rotates about the axis of the shift shaft 38 as described above.
The operation locus of the pin 34 of 0 is always constant, so that the shifting cable 70 is prevented from being shaken and the shift force can be efficiently transmitted to the transmission side. The fact that the shifting lever 30 does not move during the select operation means that the cam plate 44 of the detent mechanism 42 and the roller 48 of the leaf spring 46 do not move relative to each other, and the detent mechanism 42 is not subject to friction or the like. It is not necessary to have a configuration to deal with. Further, the select operation and the shift operation of the shift lever 50 are rotations around the respective axes of the select shaft 36 and the shift shaft 38 whose axes are orthogonal to each other in the same plane. Feeling becomes equal.

[0014]

As described above, according to the present invention, since the shifting lever does not move during the select operation, the operation locus of the shifting lever during the shift operation is always constant, and the detent mechanism for the shift operation is located on the shift lever side. Even when provided, the structure can be simplified, and the operation feelings of select and shift are improved.
